Greece's former finance minister is at the center of an escalating political scandal after three of his relatives were allegedly found missing from a list of Greeks with Swiss banks accounts that authorities are using to investigate possible tax evasion.

George Papaconstantinou, who was the main architect of debt-ridden Greece's first austerity program, was expelled from his Socialist party after the allegations came to light Friday. The party said he had "handled the list in the worst possible way." (AP)
